Abstract (en)
A gas turbine engine (10) fan outlet guide vane (34) is manufactured by diffusion bonding titanium alloy sheet metal workpieces (52,54) together to form an in integral structure (66). A titanium alloy is weld deposited at predetermined positions (70,72) and in a predetermined shape to build up bosses (42,44) at the radially outer end (40) of the hollow integral structure (68). The integral structure (66) is inflated at high temperature to form a hollow integral structure (68) of predetermined aerofoil shape. Apertures (46,48) are drilled through the bosses (42,44) to enable the radially outer end (40) of the fan outlet guide vane (34) to be attached to a fan casing (32) of the gas turbine engine (10). <IMAGE>
